Having said this, I am surprised just how little dihedral the Vlaicu Monoplane had, despite its apparent success.
It appears there are no 1:1 flying replicas and only a 1:10 model:
See video "Vlaicu RC, May 25, 2014":

As can be seen in the video, the model swings but not all the time. I also do not see it making tight turns and I do not know if its dihedral has the same opening as in the case of the original plane.
